A Team Built on Stability and Collaboration

When you join Cancer Centers of Southwest Oklahoma, you become part of an established physician group with genuine depth. The medical oncology and hematology team currently includes eight board-certified or board-eligible physicians, each bringing distinct experience and perspectives to patient care. This is not a practice where you will work in isolation or shoulder an unsustainable patient load. Your colleagues have built a culture of mutual support, shared decision-making, and respect for individual practice styles within a framework of high clinical standards. Many staff members describe CCSWOK as a family, and physician longevity reflects this sentiment.

Nursing Excellence Across All Sites

Robyn Lewis, RN, OCN, serves as Nurse Manager and Director of Nursing for the cancer center. She has built a highly experienced, stable oncology nursing team that physicians consistently cite as one of the program's greatest strengths.

  • Lawton: approximately 22 nurses
  • Duncan: approximately 10 nurses
  • Altus: approximately 5 nurses
  • Chickasha: approximately 2 nurses

The nursing team manages multi-layer chemotherapy safety checks, including independent order verification, BSA recalculation, and pathology confirmation before treatment.

Comprehensive patient education packets and a patient-facing treatment app allow families to follow care plans and stay informed.

Operational Leadership

Lane Hooton serves as Chief Operating Officer and Oncology Service Line Leader.

He oversees day-to-day operations across all CCSWOK locations, manages financial performance, and coordinates physician recruitment and onboarding. His pharmacy background ensures that drug access, safety protocols, and operational systems run smoothly, removing administrative friction so physicians can focus on patient care.

You will join a team where low turnover, high engagement, and genuine pride in the program create an environment where physicians stay long-term and patients receive consistent, compassionate care from providers who know them.
